Top 5 Foods You Should Eat Only When They're In Season

Often referred to as a "superfood," blueberries certainly live up to the hype. Blueberry season generally takes place in the summer, peaking on the East Coast around July or August. The state of Maine is the biggest producer of blueberries in the world. The berries love its acidic soil.

According to a 1997 study of fruits and veggies by the U.S. Department of Agriculture, blueberries ranked No. 1 for antioxidants. Their saturated blue-purple hue comes from the incidence of the flavonoid anthocyanin, which also fights cancer and heart disease. Blueberries are low in calories -- about 40 per serving -- and contain anti-inflammatory compounds as well.

Blueberries freeze nicely, so it's worth stocking up during the season. Because they are so fragile, don't wash them until right before using.
